Quantification and characterization of microplastic originating in the emirate of Abu Dhabi, United Arab Emirates
AI summary Read the abstract
Researchers monitored microplastic content in face washes and body scrubs sold in Abu Dhabi from 2019 to 2021, finding that the percentage of products containing microplastics dropped from 30% to 12% over this period, likely due to regulatory pressure. Cutting boards used by local butchers were also identified as a previously unreported source of microplastic contamination in meat.
The abundance of microplastic (MP) from three different sources was evaluated within the Emirate of Abu Dhabi. MP in face wash and body scrubs available in the local markets o the Emirate of Abu Dhabi were monitored over a period of three years (2019 to 2021). It was found that the percentage of MP containing cosmetic products dropped from 30% (2019) to 12% (2021). Many of the MP containing products were imported goods. Surprisingly, plastic cutting boards were found to be a source of microplastic contamination in meat and the environment. For seven meat samples from three local butchers and supermarkets, an average 1.19±0.41 mg of MP per gram of meat were found. It was noted that about 50% of these MPs will wash down into the drain, enter the sewage system and reach wastewater treatment plants, rivaling the emission of MPs from cosmetics. Finally, MP in road dust and soil was also investigated. Microtires and fibers were the most abundantly present MP in the samples. On the average, 61.4 MP particles were found in per g of road dust and road soil in Al Ain, Abu Dhabi and its environs.

Trends of microplastic abundance in personal care products in the United Arab Emirates over the period of 3 years (2018–2020)
AI summary Read the abstract
Analysis of 163 personal care products sampled from UAE markets in 2019-2020 found a modest decline in microplastic-containing products compared to a 2018 baseline, suggesting that regulatory pressure and voluntary industry reformulations have begun reducing microbead use. Polyethylene remained the dominant microbead polymer, though several new synthetic polymers appeared in newer formulations.

Researchers assessed microplastic content in 103 personal care and cosmetic products (body scrubs and face washes) randomly sampled from markets in Punjab, Pakistan. They found that 45.6% of products contained plastic microbeads, with polyethylene microbeads present in 42.7% of products, and a higher prevalence in imported products compared to locally manufactured ones.
Microplastic pollution in marine waters and sediments of Abu Dhabi Emirate, UAE
AI summary Read the abstract
Scientists found tiny plastic particles in the water and sand around Abu Dhabi, with the highest levels near oil operations, ports, and islands. These microplastics—which are smaller than a pencil eraser—come from everyday items like plastic bottles and fishing nets that break down over time. This matters because these tiny plastics can enter the food chain through fish and shellfish that people eat, though more research is needed to understand the full health effects.
